Evaluación del Impacto de Fibras de Material Reciclado y Naturales en la Resistencia del Concreto.

Abstract

Abstract

This research aims to evaluate the impact of steel fibers on plain concrete and their behavior as an integral part of any type of structure.

Within the field of civil works construction, hydraulic concrete is perhaps the most widely used material, and therefore various types of research have focused on evaluating the behavior of its physical-mechanical properties by incorporating natural or artificial fibers.

The design of the plain concrete mix was carried out, based on the correct analysis of the materials to be used, and with their respective test mixes to evaluate workability and strength.

To obtain reliable results in the development of the research, a pilot sample is used to indicate if the specimens evaluated are conclusive enough to obtain reliable and representative data. Additionally, the incorporation of fibers in different quantities per cubic meter of plain concrete is experimentally carried out to verify their incidence in the new product, thus carrying out the corresponding analyses in terms of modulus of rupture and compressive strength.

Once the final product is obtained, an economic estimation is performed, which takes as its base price the value per cubic meter of plain concrete, and the increase in direct costs as the amount of fiber added per m³ of fiber-reinforced concrete varies.

To correlate the values obtained in terms of compressive strength with their respective modulus of rupture equivalent, we start from statistics and its tools to obtain, through different regressions, a reliable correlation coefficient that relates the two variables being analyzed.

Keywords: Concrete, fibers, flexural, strength.
